Walking at night alone (around 23:00 to 4:00) at the center of Ho Chi Minh (mostly district 1), so many touts tried to get me on their bike. I have never got on it, but it might be that they talk to me since I look like a foreigner.
They usually talk to me in English (e.g. Can I help you?Can I help you? or Where are you going?), or something like "Hey" to get my attention.
But I feel that there is no meter on the bike, and it sounds unreliable to begin with.
Is this a tourist scam? Is it safe to get on their bike? How is the fare calculated? Or do they get me to the correct destination like a taxi, in the first place?
